Overview of Thermalright CPU Coolers
The Thermalright Assassin X120 Refined SE CPU Air Cooler is priced at $17.90, making it a budget-friendly option for users seeking effective cooling. In contrast, the Thermalright PS120SE ARGB CPU Air Cooler is more expensive at $34.94, costing about 95% more. This price difference reflects the additional features and technology present in the PS120SE, which may appeal to those looking for enhanced aesthetics and performance.
Cooling Performance
The Thermalright PS120SE ARGB boasts an advanced cooling setup with 7 heat pipes compared to the 4 heat pipes found in the Assassin X120. The PS120SE uses upgraded AGHP 4.0 technology, which helps mitigate the inverse gravity effect, ensuring efficient heat dissipation regardless of orientation. Both coolers provide a maximum airflow of 66.17 CFM, but the PS120SE’s additional heat pipes may allow it to handle higher thermal loads, making it a potentially superior choice for overclocking or high-performance builds.
Fan Technology
The Assassin X120 utilizes a TL-C12C PWM fan, which operates at a maximum speed of 1550 RPM and maintains a noise level of ≤25.6 dB(A). On the other hand, the PS120SE features dual TL-C12B-S V2 PWM fans, with a slightly lower maximum speed of 1500 RPM but still achieving the same noise level. The dual fan setup in the PS120SE can provide improved cooling through enhanced airflow, making it a better option for users who prioritize quiet operation alongside effective cooling.
Design and Aesthetics
When it comes to design, the PS120SE clearly stands out with its ARGB lighting capabilities, offering up to 17 different light modes that can be synchronized with other components. The Assassin X120, while effective, does not include any lighting features, making it a more utilitarian choice. Users who appreciate a visually dynamic setup will likely prefer the PS120SE for its aesthetic appeal, even if it comes at a higher cost.
Compatibility and Installation
Both coolers are compatible with a wide range of CPU sockets for both Intel and AMD platforms, including Intel's LGA 1150/1151/1155/1200/1700 and AMD's AM4/AM5. The Assassin X120 has a height of 148mm, while the PS120SE is slightly taller at 154mm. Despite this small difference, both coolers are designed to fit in mid-sized cases. The installation process for both products is facilitated by the inclusion of appropriate mounting plates and fasteners, ensuring ease of use for builders of all skill levels.
Build Quality and Durability
Both the Assassin X120 and PS120SE are constructed with aluminum heatsinks and feature S-FDB bearings, which enhance durability and ensure a long service life of up to 20,000 hours. The PS120SE, however, incorporates more advanced materials, such as anodized black frosted tops and finely carved copper bases, which may contribute to better long-term performance. The quality of materials used in the PS120SE suggests that it may offer enhanced thermal conductivity and longevity.
Price Comparison
The price difference between the two coolers is significant, with the Assassin X120 retailing at $17.90 and the PS120SE at $34.94. This represents a difference of about $17.04, or approximately 95%. While the Assassin X120 offers great value for those on a budget, the PS120SE justifies its higher price with additional features such as enhanced cooling performance, dual fans, and customizable RGB lighting, which may attract users looking for premium performance and aesthetics.
Which should you buy?
Choosing between the Thermalright Assassin X120 Refined SE and the Thermalright PS120SE ARGB CPU Coolers ultimately depends on your specific needs and budget. If you are looking for an economical and effective cooling solution, the Assassin X120 is a solid choice at $17.90. However, if you desire advanced cooling capabilities, aesthetic features, and slightly better performance, the PS120SE at $34.94 may be worth the investment. Ultimately, the decision hinges on whether the premium features of the PS120SE align with your preferences and requirements.
